I know that the official datasheet for the 328 says that the minimum voltage for 16mhz is 3.84V or something like that, but I was wondering if it would be safe to run just a little lower. Going down to 3.6V would make my project use fewer parts and work much better, and I know the arduino will run like that
...I just don't know how long it will run. AFAIK, the chip is rated at about 10 years of running 24-7; my goal is to run this project for 5 years, also 24-7. Am I going to have problems down the line?
